40V trench MOSFET has an integrated soft recovery diode

Thanks to its integrated soft recovery diode (SRD), Toshiba's TPH1R204PB 40V trench MOSFET is able to keep the spike voltages generated between the drain and source during switching very low.

This makes the MOSFET suitable for synchronous rectification in the secondary side of switching power supplies that require low EMI. Target applications include high-efficiency AC-DC and DC-DC converters as well as motor drives, for example in cordless tools. The TPH1R204PB is an N-channel device with a maximum on resistance (R DS(ON)) of only 1.2mΩ (at V GS of 10V). Rated output charge (Q OSS) is just 56nC. The device is supplied in a SOP advance package measuring just 5x6x0.95mm.
